Patented July', 1914.,

To all whom it may concern:

Be it known that I, CLAUDE SINTZ, a ci'tizen of the United States of America, residing at Detroit, in the county of Wayne Aand State 'of Michigan, have invented certain new' and useful Improvements in Driving-v lVheels; and I do. hereby' declare the following to be a` full,clear, and exact description of the invention, such' as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in the driving wheels of traction engines and its object is to provide the same with yieldable connections between the motor and the wheel, and to provide the same with various new and useful features hereinaftermore fully -described and particularly pointed out in the claims, reference being had to the accompanying drawings in which:

F ivure 1 is an elevation of a traction with my device attached thereto, with vportions broken away to show the construction; Fig. 2 is a vertical section of the same; Fig. 3 is an enlarged detail of a portion of the means for conwheel; Fig. 4 a detail partially in longitudidriving wheel and the traction wheel; Fig. 5

wheel is connected; and l ig. (3 is a detail o the frameon which the segment is mounted.

` Like numbers refer to like parts in all of the figures.

1 represents the axle, 2 the hub, 3 the rim, and'4 the spokes of a traction wheel substantially as usually made.

. 5 is a Wheel for driving .the traction Wheel,V4 preferably a sprocket wheel to receive a suitable' chain driven by any convenient motor. .T his wheel is provided with arms (Steight such arms being shown,) four of on the side toward'the traction wheel each lug being provided with an opening through which extends a segment 8 preferably circular in cross sections and arranged con- These segments are mounted in a curved trame S also concentric with the anis of the whe-eis and secured to the spokes i of the traction wheel by suitable clips and bolts as show inA Fig. 3 each fr? provided with in ids in which the se() nient 8 is fixed, anc.k each segment in place it is provided at one ende with a conical or tapered portion- 8 and a key 1 0-to engage suitable openings 11 in one of. the lugs 12 and is forced -into such opening by a Wedge block 14 inserted in a recess 15 in the-end of the frame and held therein by one of the "clips or bolts as shown inFig. 3. Each armv 6 is yieldably held normally in mid-position on the respective segment 8 by means of springsV A13 surrounding-the segment and located between the lug on the 'arm andthelugs 12 on the frame 9. The wheel thus has a and while rotatin withV the same also rotates slightly relatlve to the rotation of the traction wheel whereby the'driving stress operates to compress the springs, the lugs 7 Vsliding on the` segments 8 whereby sudden ment. relative. to the tractionI Wheel and nor! mally rotating therewith, segments fixed on 'one of the said Wheels,rthe` other o said wheels having lugs surroundingthe seg ments, and springs engaging'thelugs to yieldably hold the same in normal midposition andslidable on. the segments.

2. The combination of a traction wheel` and -a drivin Wheel arranged cci-axially,

-le driving W eel-havinga limited rotary movement relative to the traction Wheel and normally rotative therewith, segments mounted on the 'spokes of the traction wheel,

the spokes of the driving wheelhavin lugs surrounding the segments and. shdable thereon, and opposing springs on the segments engaginthe lugs, to -yieldably hold the same in mi-position on the segments.

3. The combination of a traction Wheel and a drivinY wheei arranged co-axially, the driving whee having a limited rotary Inovenent relative to the traction wheel and' normally rotating therewith, frames mounted he spokes of the traction wheel, segs mounted on the frames concentric the axis of the wheels, the respective ends of the frames having lugs snpportin the segments, they spokes of? the driving Whee also having l slidable on the segments, and opposing` n the lug 'yieldable connectionwith the traction Wheel 'end and engaging the lugs at the respective ends of the frame at the other end.

4. The combination of a tract-ion wheel and a driving wheel arranged 3o-axially, the driving wheel having a limited rotary movement relative to the traction wheel and normally rotating therewith, a frame mounted on thespokes of the traction Wheel, the respective ends of the frame, each provided with a lug having an opening, a segment mounted in said frame concentric with the axis of the wheel, one end of the se ent having a `conical portion and a key fitting in one of said., openings, a wedge block engaging the end of the segment to secure it in 15 sald openings, clips to secure the frame to the spokes of the traction wheel, bolts to seeure the clips and Wedge block, on thedriving Wheel having a lug slidable on the segment, and springs on the segment bein presence of two witnesses.
